In the results and discussion that follow, we take advantage of the activation paths generated by the dynamics of the model, induced by inputs, i.e. activated pixels from MNIST digits. The resultant computed paths are used with or without spike-timing-dependent plasticity (STDP) ([1]}, [2]}) directly (sections REF  and REF ) or with STDP on the weights (section ) to encode features for back end classifiers.
